CC -!- FUNCTION: This protein is a bile pigment-bearing rod linker polypeptide
CC that associates with C-phycoerythrin.
CC -!- SUBCELLULAR LOCATION: Cellular thylakoid membrane; Peripheral membrane
CC protein; Cytoplasmic side. Note=Periphery of the rods of the
CC phycobilisome.
CC -!- PTM: Contains one covalently linked phycourobilin chromophore.
